Question

Three cards with holes are arranged in a straight line. A light is shined through the first card’s hole and travels through all three cards. What does this tell you about light rays? A) that light is reflected B) that light is refractive C) that light travels in a straight line D) that light does not travel in a straight line

Answer 1

C) that light travels in a straight line.

Answer 2

that light travels in a straight line

Step-by-step explanation:

The fact that the light shone through the first card hole travels through all three cards shows that light travels in a straight line. This phenomenon is known as the rectilinear propagation of light.

If uninterrupted, light shone at one cardhole moves straight through all the cardholes in a straight line.
